HTTP/3: send Stream Cancellation instruction.
As per quic-qpack-21:
When a stream is reset or reading is abandoned, the decoder emits a
Stream Cancellation instruction.
Previously the instruction was not sent. Now it's sent when closing QUIC
stream connection if dynamic table capacity is non-zero and eof was not
received from client. The latter condition means that a trailers section
may still be on its way from client and the stream needs to be cancelled.
